To get you up to speed, Petraeus resigned Friday over his extramarital affair with his biographer, Paula Broadwell, which was uncovered after a second woman, Tampa socialite Jill Kelley, told a friend at the FBI that she had received threatening anonymous e-mails about her own (reportedly platonic) relationship with Petraeus. A subsequent FBI investigation revealed that the emails had come from Broadwell and that Broadwell was having an affair with Petraeus.

She now lives in Tampa, Fla., where she is an "unpaid social liaison" to MacDill Air Force Base, home to the U.S. Central Command. From what we can tell, the role is basically a fancy term for socialite, and entails organizing, hosting, and attending social events for high-ranking military officials.

She and her husband Scott, a respected cancer specialist, live in a $1.3 million colonial mansion in Tampa's upscale Bayshore Boulevard neighborhood with their three young daughters. According to the Tampa Bay Times, Jill Kelley has "established a name for herself as an extravagant hostess with a military guest list" and the Kelley mansion is "the place to be seen for coalition officers."

Although she is not a government employee, Kelley was reportedly named an honorary consulate general to South Korea in September, and in a photo taken by the Daily Mail, she is pictured with a Mercedes with a license plate that reads "Honorary Counsel." The AP reports that she was also presented with a certificate awarding her as an "honorary ambassador for allied nations," and uses the title, but drops the "honorary."

In the 10 years that Jill and Scott Kelley have lived in Tampa, one or both have been the subject of at least nine lawsuits "seeking payment of real estate and credit card debts," according to the Tampa Bay Times.

According to an August story in the Tampa Bay Times, Kelley's identical twin sister Natalie Khawam, a Tampa lawyer who represents whistleblowers, is embroiled in a nasty lawsuit with her former employer, whom she has accused of sexual harassment and other charges. The employer has fought back with court documents claiming Khawam has a "history of abusing the litigation process." According to a bankruptcy petition she filed this year, Khawam lives with the Kelleys in Tampa, and owes $3.2 million in unpaid debt. According to the Chicago Tribune, Khawam was also involved in a brutal custody fight with her former husband, Grayson Wolfe, a Washington, D.C.-based venture capitalist who once worked for the Coalition Provisional Authority in Iraq. The New York Post reports today that Petraeus wrote a letter in support of Khawam to the court in the case, although we have not been able to confirm this. According to the Post, the judge called Khawam a "psychologically unstable person," and awarded Wolfe sole custody of the 3-year-old child the couple.

Kelley triggered the FBI investigation into Petraeus — and subsequently Allen and herself — when she told a friend in the FBI about the email threats. That FBI agent was removed from the case, after his supervisors decided he had become infatuated with Kelley. The agent also sent Kelley shirtless photos of himself, although accounts differ on whether the photos were sent before or after she told him about the Petraeus emails. (To make matters weirder, that same FBI agent contacted Washington Republican Congressman Dave Reichert in late October to tip him off to the Petraeus scandal, after the agent became convinced that the harassment case was being stalled as part of a coverup to protect Obama.)

But there are still quite a few unanswered questions about Kelley and her relationship with two of the nation's leading military and intelligence officers — not least of which is what could possibly be in the thousands of pages of correspondence between her and Allen.
